Cleaning The Filter - American Standard HPWH50G-AS Owners And Operation Manual

Flushing Tank:
A water heater's tank can act as a settling basin for solids suspended in the water. It is therefore not uncommon
for hard water deposits to accumulate in the bottom of the tank. To clean the tank of these deposits, open the drain
valve located under the large decorative cover near the bottom of the unit and drain a few quarts of water from the
water heater every month.
Attach a garden hose to the drain valve located at the bottom of the unit and direct that hose to a drain. Allow
several gallons to flush through the discharge line into an open drain. The decorative front cover must be removed
to access the valve. In order to drain the water heater completely, turn off the cold water supply and open a hot
water faucet or lift the handle on the relief valve to admit air into the tank.

Operation and controls should be checked by qualified service personnel. Make certain the water heater is
completely filled again before placing it in operation.

CLEANING THE FILTER

In the Auto and Eco modes, the heater moves air through the system and out the top of the unit. The filter is in place
to protect the evaporator from dirt and dust. A clean air filter is important to get the highest efficiency. Occasionally
this filter will need to be cleaned (at least once a year). When the filter requires cleaning, the red light above the filter
button will be illuminated and an audible beep will sound. The screen will display instructions that the filter needs to
be cleaned. When this screen displays this message, you can press the arrow button for instructions on how to clean
the filter.
Leave the power on and remove the filter from the top of the unit. It is located in the top of the unit behind the hot
and cold inlet pipes. Grasp the plastic handle and slide the filter straight up until it clears the cover. Once it has been
removed, the filter can be wiped clean with a damp rag or rinsed with warm water. Once the filter has been cleaned,
it can be replaced by aligning it into the slot in the top of the unit and sliding it down into place, when the handle is
flush with the top of the cover, it is seated. When the clean filter has been reinstalled, press the FILTER button and
then press ENTER.
IMPORTANT: The filter must be cleaned when the alarm is displayed. A dirty filter will make the
system work harder and result in a reduction of efficiency and possible damage to the system. In order to get
the best energy efficiency available, make sure your filter is clean.
